Description
ELBOW FITTING PART
The invention relates to an elbow fitting part for upper arm stumps, an elbow ball being connected by a hinged axle to the lower arm, configured as a hollow synthetic part, and being detainable by a latch-locking device in various bending positions, while the proximal connection to the upper arm shaft is created by means of a cast-in ring and an upper arm rotating joint is provided for the adjustable rotation of the lower arm.
Known elbow fitting parts exhibit an upper arm rotating joint in the form of a sickle joint configured as a plane bearing and are therefore only suitable for limited upper arm stump lengths. In order to cater to long stumps, elbow fitting parts without a sickle joint are used. Where these previously known elbow fitting parts exhibit a latch-locking device, this engages into a catch disposed on the outer periphery of the elbow ball.
The object of the invention is to design the elbow fitting part described in the introduction such that it is suitable for all upper arm stump lengths.
According to the invention, there is provided an elbow fitting part for upper arm stumps, an elbow ball being connected by a hinged axis to a lower arm, which is constructed as a hollow plastics part, and the elbow ball being lockable in various bent positions by a latch-locking device, while the proximal connection to the upper arm shaft is made by way of a cast-in ring and an upper arm rotary articulation arrangement is provided, constructed as a ring bearing, for the adjustable rotation of the lower arm, wherein a) the latch-locking device is a traction lock which is arranged outside the elbow ball and is integrated in a rotary connection forming a section of the hinged axis arrangement; b) the upper arm rotary articulation arrangement comprises a bearing ring which is inserted in the elbow ball and connected non-rotatably thereto, which has an annular projection surrounded by a brake ring which is non-rotatably ~3' connected to the cast-in ring, the latter being rotatable by - about 180~ with respect to the bearing ring; c) the brake ring can be acted upon by a braking piece which bears against a chamfered surface of an annular edge of the brake ring, this chamfered surface extending peripherally over about 180~
and defining the pivotal range of the cast-in ring; d) the brake piece can be tensioned radially against the braking ring by way of an externally accessible screw; e) the bearing ring radially overlaps the elbow ball by means of an annular flange on which the cast-in ring is supported.
The measures according to the invention enable the needs of patients having any optional stump length up to elbow exarticulation to be met with only one rotating joint, for the configuration of the upper arm rotating joint as an annular bearing instead of the previously used plane bearing means that the necessary space is acquired for virtually any optional stump length. As a result of the externally disposed traction lock, the geometry for long stumps is guaranteed; no constructional adaptation to different stump lengths is necessary.
Further features form the subject of the subclaims and are explained in greater detail in connection with further advantages of the invention, with reference to an illustrative embodiment.
One embodiment of the invention, serving as an example, is represented in the drawing, in which:
FIG. 1 shows an elbow fitting part in side view and partly in longitudinal section;
FIG. 2 shows the representation according to FIG. 1 rotated by 90~ and in longitudinal section;
FIG. 3 shows, on an enlarged scale, a detail from FIG. 2;
FIG. 4 shows, in exploded representation, a traction lock assembly;
FIG. 5 shows, in top view, a traction lock linked to a hinged plate bar;
B
~_ ~n~
FIG. 6 shows, in exploded representation, a further assembly of the traction lock according to FIG. 5;
FIG. 7 shows a brake ring in top view and FIG. 8 shows a section view taken along the line A-A in FIG. 7.
The elbow fitting part represented in FIGS. 1 and 2 essentially comprises a lower arm 1, which is configured as a hollow synthetic part and at whose upper end an elbow ball 2 is mounted pivotably about a hinged axle 3 and can be detained in various bending positions by a latch-locking device. For the proximal connection to an upper arm shaft (not represented), a cast-in ring 4 is provided, which is part of an upper arm rotating joint for the adjustable rotation of the lower arm 1 equivalent to bending of an elbow. When the lower arm 1 swings freely, the extension is limited by a front stop which is made of Perlon wire 5 and which is fastened on the one hand to the elbow ball 2 and on the other hand to the lower arm 1.
The upper arm rotating joint comprises a bearing ring 7, which is inserted into the elbow ball 2 from above and is fixed against rotation within the elbow ball 2 by means of screws 6 and exhibits an annular projection 8, which is embraced by a brake ring 9 connected to the cast-in ring 4 and fixed against rotation therewith by means of screws 10.
An annular edge 11 of the brake ring 9 projects radially inwardly beneath the annular projection 8. This arrangement enables the cast-in ring 4 to be held securely against axial separation on the elbow ball 2, but allows the cast-in ring 4 to rotate around the end of the elbow ball 2. As will be seen from Fig. 7, the brake ring 9 has a gap at one location around the ring and has a number of radially penetrating, axially directed slots on the inner surface of the ring at a location opposite to the gap. This allows the brake ring 9 to be expanded so that the annular edge 11 may be allowed to clear the annular projection 8 during assembly or disassembly of the device. The annular edge 11, facing the elbow ball 2, of the brake ring 9 exhibits a chamfered surface 12 over 180 peripheral degrees (see Figs. 3 and 7), against which : chamfering a braking piece 13, consisting for example of a nonferrous metal, can be braced radially by means of a screw connection 14 which is accessible from the outside. The braking force exerted upon the brake ring 9 by the braking piece 13 can be reset according to the desires of the user by adjustment of the screw connection 14.
The bearing ring 7 radially overlaps the elbow ball 2 by virtue of an annular flange 15, which supports the cast-in ring 4 (see in particular FIGS. 2 and 3), in a manner that allows the cast-in ring 4 to be rotated. By virtue of the chamfering 12 of the brake ring 9 over 180~ and the engagement of the braking piece 13 with the chamfered surface 12, the rotation of the cast-in ring around the elbow ball 2 is limited to 180~.
The hinged axle 3 is formed by two mutually aligned rotating connections, by means of which the elbow ball 2 is mounted pivotably between two hinged plate bars 16 which are firmly connected by means of screws 18 to lateral rails 17 integrated into the lower arm 1. Each rotating connection exhibits a hinge pin 19 (see Fig. 4), which bears by means of a head 20 externally against the assigned hinged plate bar 16 (latch-free rotating connection) or against a housing 23 of the latch-locking device and is screw-connected (screws 22) by its other end to a lug 21 of the bearing ring 7. Outside the elbow ball 2, a latch-locking device in the form of a traction lock is integrated into the one rotating connection forming the hinged axle 3. The latch-locking device is mounted, with the housing 23, on the assigned hinged plate bar 16 such that it can be twisted on the one hinge pin 19, as is shown by FIG. 5. According to the exploded representation in FIG. 4, the housing 23 and the hinged plate bar 16 enclose between them a dog 24, a pressure spring 25, a latch disk 26 and a switch spring 27 (see FIG. 6).
Incorporated into the housing 23 is a drawer 28, which closes off the housing 23 by means of a flange 29 and comprises a wedge 31, the wedge being displaceable counter to ~' '~.
: 5 the action of a pressure spring 30 and actuating pawls 32 -which are acted upon by pressure springs 33. Assigned to the wedge 31 is the switch spring 27.
The wedge 31 exhibits at its one end a threaded pin 34 which is placed through the flange 29 and through a thereto attached connecting piece 29a of the drawer 28. Onto this threaded pin 34 there is screwed a traction cable 35 (represented in FIGS. 1 and 2), to whose free end there is fastened a clamp 36 for the manual actuation of the traction lock.
The traction lock can be released by tightening of the clamp 36; the elbow ball 2 is freely pivotable between the hinged plate bars 16 in relation to the lower arm 1. Renewed tightening of the clamp 36 produces a latch-locking of the elbow ball in the desired bending position, eighteen latch-locking positions, for example, being able to be provided.
